Researchers Develop New Temperature Switchable Membrane

Researchers from the University of Connecticut and Yale University have developed a new membrane with highly aligned nanoscale pores that open and close in response to temperature; this highly porous, valve-like material has many potential filtration applications, including water purification and molecular separation. The membrane was created from a block copolymer that self-assembles into alternating […]

New Materials Have the Ability to Quickly Change Colors and Textures

A team of engineers has developed a new synthetic material that can change its fluorescence and texture in response to a change in voltage applied to it. Cephalopods, which include octopuses, squid, and cuttlefish, are among nature’s most skillful camouflage artists, able to change both the color and texture of their skin within seconds to […]

Invisibility Cloaks Closer to Reality

A newly published study details how “digital metamaterials” could help bring invisibly cloaks closer to reality. The concept of “digital metamaterials” – a simple way of designing metamaterials with bizarre optical properties that could hasten the development of devices such as invisibility cloaks and superlenses – is reported in a paper published today in Nature […]

Researchers Discover Mechanism Behind Solid-Solid Phase Transitions

An international team of researchers helps uncover mechanism behind solid-solid phase transitions, providing new insight for all sorts of solid-solid phase transformations. Two solids made of the same elements but with different geometric arrangements of the atoms, or crystal phases, can produce materials with different properties. Coal and diamond offer a spectacular example of this […]

Graphene Paint Can Make Impermeable and Chemically Resistant Coatings

New research from the University of Manchester demonstrates how a thin layer of graphene paint can make impermeable and chemically resistant coatings, which could be used for packaging to keep food fresh for longer and protect metal structures against corrosion. The surface of graphene, a one atom thick sheet of carbon, can be randomly decorated […]

New Nanotechnology Aids in Cooling Electrons Without External Sources

Using a nanoscale structure that consisted of a sequential array of a source electrode, a quantum well, a tunneling barrier, a quantum dot, another tunneling barrier, and a drain electrode, researchers were able to suppress electron excitation and cool electrons to -228 °C without external means at room temperature. A team of researchers has discovered […]

Researchers Synthesize 2D Material Germanene

A newly published study details how a team of researchers successfully synthesized the 2D material germanene for the first time. Dubbed a “cousin of graphene”, the material, which is made up of just a single layer of germanium atoms, is expected to exhibit impressive electrical and optical properties and could be widely integrated across the […]

New Type of CNT Solar Cell is Twice as Efficient as Past Models

Material scientists from the McCormick School of Engineering at Northwestern University have created a new type of carbon nanotubes solar cell that is twice as efficient as its predecessors. Lighter, more flexible, and cheaper than conventional solar-cell materials, carbon nanotubes (CNTs) have long shown promise for photovoltaics. But research stalled when CNTs proved to be […]
